C#：异常 - 参数无效 - 表单 Dispose 方法

在处置时object of a form从另一个exception正在投掷像Parameter is not valid

访问第二种形式的代码

        Assembly X = Assembly.LoadFile(Application.StartupPath + "\\Test.dll");
        Form frminv = (Form)X.CreateInstance("Test.Form1");
        frminv.Dispose();

这是表单处理方法（来自Designer.cs）

protected override void Dispose(bool disposing)
    {
        if (disposing && (components != null))
        {
            components.Dispose();
        }
        base.Dispose(disposing);// exception is thrown from here
    }

这是堆栈跟踪

将会出现什么问题。 请帮我。

我必须查看代码才能确定，但​​也许我可以帮助您查找正确的位置......

堆栈跟踪表明在 Dispose 序列期间发生了 pictureBox 中动画的重绘。那么，为什么图片框应该在它应该死掉的情况下尝试这样做呢？

在这些情况下，您可能需要执行以下操作：在处理窗口之前关闭（）窗口，彻底关闭窗口（例如，在调用 base.Dispose() 之前禁用图片框中的动画），或者可能还有其他资源在您的类中创建并需要在您可以安全地调用 base.Dispose 之前进行处置。或者，您可能已经处理掉了仍然需要的东西（例如，pictureBox 试图访问的图像） - 检查处理“组件”实际上会处理什么。
